ICE-QALK;

Specification forming part of Letters Patent No. 37,788, dated lit-ln'nary 24, lSFZi.

To (LZZ whom, it may concern:

Be it known that I, DANIEL KRAUSER, or Pottsville, in the county ot` Schuylkill and State of Pennsylvania, have invented a new and improved ealk or creeper to be attached to boots and shoes to prevent persons slipping lowing is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making apart of this specication, in which- Figure l is a detached face view of my invention. Fig. 2 is a side sectional view of the same applied to a boot or shoe, x m, Fig. 1, indicating the line of section.

.Similar letters of nreference indicate corresponding parts in the two figures.

This inven-tioieeensistsin havin-g a series ofspurs attached to a plate, which is connected by ajointto a frame or clamp so constructed that it may be readily attached. to the heel oi' a boot or shoe, said frame or clamp having a spring attached to it, and all so arranged that the plate which is provided with the spurs will be capable of being turned over on the heel and the spurs serve as foot-holds, and the plate, when the spurs are not required to serve the above office, be capable ot' heilig turned over in the hollow of the sole, so that the spurs will be entirely out of the way.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a frame, constructed of metal and in the form of a heel ot a hoot or shoe, so that. it maybe iitted thereon, and secured in proper position by a screw, B, which passes through the back ot' the frame and bears against the hack of the heel so as to draw the front part of the frame in close contact with the front of the heel. The inner side of the front part of the frame is provided with points (r spurs a to insure the firm connection of the frame to the heel. (See Fig.`2.) The sides b b of the 'frame A project some distance in front of the front bar, c, of the same, and through the sides Il b, near their ends, arod, d, passes. `On this rod d two square lugs or ears, e e, ot' a plate, C, are fitted loosely: rJhe lugs or ears e e project at right an gies from the plate C--onc at eachsideand against said lugs or ears a spring, D, bears, which is attached to the outer side of the bar c of the frame A. This spring I) may be formed otl a tlat metal plate, of a properthickness to have the requisite elasticity. The plate G is nearly equal in 'width to the frame A, and to one side oi' it there are attached a4 series of spurs or points, f. The lugs or ears c c, in consequence of being fitted loosely on the rod d, form a joint for said plate, and admit of it being turned over on the heel of the boot or shoe, as shown in Fig. 2, or being turned over in the hollow of the sole, as shown in red in the same iigure, the heel and sole being also shown in red. The spring D, in consequence of bearingr against the lugs or ears c c of the plate, retain the saine in either of the two positions mentioned. YVhen the implementis in use, the plate C is turned ovtr on the heel of the boot or shoe, the spurs or points f projecting down from the plate and serving as an eiiicient foothold, as shown in Fig. l, and when not required for use the plate is turned over into the hollow ofthe shoe.

The advantage of this invention over others of the same class is that the spurs or pointsf are not at all in the way nor allowed to serve as an ineulnbrance when not required for use, as a simple adjustment of theplate U removes them from the heel.

I am aware that an adjustable serrated bow has been previously devised to eii'ect this result, but in that arrangement the bow when in use was in the hollow of the sole, and consequently could not operate perfectlyespe ciall y if applied to high-heeled boots or shoes; besides, the hollow ofthe sole is not the proper piace for the spurs or points. They cannotiu that place eii'ectually prevent slipping, for the reason that in walking the heel at each step touches the ground first; and in case lowheeled boots or shoes are used, the serrated plate will project too low and give a rocking motion to the foot, which is very unpleasant to the wearer. I am also aware that another form of device has been used, in which the spurs are concealed beneath the hollow of the foot when not in use, and are placed behind or around the heel when in use.

I do not claim anydevice in which the spurs, when in use, are outside` the area of the heel, one object of my invention being to give the heel adirect bearing upon the spurs.

I do not claim, broadly and irrespective of the construction and arrangement herein shown and described, an adjustable plate provided with spurs or projections to serve asa foothold for a boot or shoe; but

I do claim as new-and desire to secure by nLetters Patent- A The heel-frame A, in combination with. the flat plateG, when the latter is so attached ro the foriner and arranged in such relation therewith as .to admitof being placed directly.

beneath the heel when the spurs or points f are requircdfor use, and admit of being turned over into the hollow of tl e sole when not required for use, substantially as shownand described.
